771180fd28 feat: iterations 19 + 17 — Float/Bytes scalars (.wob v5), library kind + internal/
- Float full stack: literals (fraction/exponent; `0..10` still a range), f64
  opcodes 34-41, @table column, WAL bit-exact replay, json fractions in and
  shortest-round-trip out. IEEE-quiet — FDIV never traps where DIV does.
- Bytes: a wo_str with its own class id, so alloc/free/copy are shared but no
  Text builtin accepts one; len/at/slice/eq/concat, base64 both ways, json
  boundary as base64; TEXT_COPY preserves the kind.
- No implicit Int/Float mixing (WO-E201 in the typechecker, not the emitter,
  which picks the opcode from one side and would misread the other).
- One IEEE deviation: float_cmp total order (NaN last, -0.0 == +0.0) for
  indexes and order-by, keys canonicalized to match. `?Float` nil is a
  reserved quiet NaN — the zero word is +0.0, WO_NIL_SCALAR's bits are -2.0.
- Renderer prefers fixed over exponential in 1e-6..1e21: pure shortest makes
  a price of 900.0 read `9e+02`. One renderer for interp/json/float_to_text.
- Fixed en route: lexer double-counted the leading digit; is_scalar_shaped
  took Float/Bytes as Int-shaped; Bytes ownership needed a shared heap-scalar
  predicate or temps never dropped; order-by bit-compared negatives backwards.
- Iteration 17: `kind = "library"` (absent = program; bad value = WO-E109),
  entry-less check mode retiring the `--emit` workaround, Go's `internal/` as
  WO-E108 at the consumer's `use`. Driver-only; VM/.wob/GC untouched.
- Framework reorg: internal/{parse,serve}.wo; http/form.wo split out to keep
  media_type/form_values public (parse.wo had grown public surface).
- Docs: link audit (97 -> 88 broken, conflict markers resolved, 2 duplicate
  stories removed), 00-code-review verified 26/27, iterations re-sequenced.
- Also carries the pre-staged pub(read)/using/#if work from the index.
- Gates: corpus 103/0, test_wal 156/0, web-app 26/0, oop-accept ALL MET.

77c9090ce5 feat: spawn / send / actor M — the unified actor surface (arc T3)
- language: `spawn Cls { fields }` expression (ctor semantics — fields
  MOVE; result is the address); `actor M` parametric field type
  (contextual like multi/map — actor stays a legal identifier); `send`
  is a builtin free-fn name, not a keyword (shadowing rule applies)
- typing: M inferred from Cls's receive(msg: M); WO-E221 when receive
  is missing, mis-armed, or M is not a class/record/union; send checks
  addr is `actor M` and the message IS an M (silent when underivable);
  ctor half of spawn delegates to the Ctor arm (completeness, ?T, E207)
- ownership: send's message TRANSFERS (sender's later use = WO-E301,
  corpus-pinned); spawn's fields move via the ctor machinery; an
  address is Copy
- emit: spawn lowers to ctor + LOADK receive's method index + BUILTIN
  68; send is BUILTIN 69 with the message excluded from fresh-arg drops
  (the runtime owns it now)
- runtime: wo_actor (moved-in instance, receive idx, growable FIFO
  mailbox, one delivery fiber at a time); delivery reuses the fiber
  context across messages and re-queues per message (fairness — an
  actor never monopolizes); the runtime drops each message after its
  receive returns; actor state/queued/in-flight messages are GC roots;
  teardown drops everything (main-return reap included); loader knows
  the two arities
- corpus: run/actor-echo (typed spawn/send, one-at-a-time delivery
  interleaved with main by budget — output exact, ASan-clean),
  compile-fail/spawn-no-receive (WO-E221), send-after-move (WO-E301)
- battery green: oop-e2e 92/0, woc-test, wovm-test, log-watcher 7/0,
  employee 8/0, web-app 21/0, deps-accept 8/0

6ff119cd57 fix(compiler): storing an owned value in a container is a MOVE
The disclosed "move-on-push" gap detonated on iteration 16's route-table
pattern: `push(self.routes, r)` moved the Route into the container while the
`take r` parameter's scope-end DROP still fired — the container's own drop
plan (multi_free) then freed the element a second time. ASan: SEGV in
class_free during trap unwind; latent until now because pushed elements were
Texts, which copy at the boundary (2026-08-14).

owner.ml analyze_call: `push`'s value slot and `set`'s key/value slots now
TRANSFER an Owned, non-copy-stored place (record_move, exactly the take-arg
shape), so the pusher's drop disappears. Text/json.Value keep the copy-store
path (stores_by_copy) and the caller still drops the fresh copy. Traced (gc)
values remain exempt (tracing owns them). A user-declared push/set fn of the
same name wins, per the builtin shadowing rule.

Pinned by tests/corpus/run/container-owned-move (route table: interface-
typed field values pushed via take params, dispatched by ICALL, mixed with
Text pushes) — the exact iteration-16 shape, ASan-clean.

Verified: woc-test 540/0; oop-e2e 88/0; log-watcher 7/0; employee 8/0.

4a62488bc6 feat: retire RC from the emitter and the format — .wob v4 (7b Phase 3b)
The compiler no longer emits reference-counting ops anywhere, and the format
reserves them. With Phase 3a's collector this completes the runtime half of
iteration 7b: spec success criteria 3 (no RC ops in any image, opcodes
reserved) and 6 (corpus ASan-clean) are met — `just oop-accept` is fully green.

- owner.ml: the rc machinery is deleted outright — rc_site/rc_op types, the
  rcs table, fn_rcs/rc_groups/rc_escaped, record_rc, release_gc, gc_escape,
  resolve_rc, and the clobber rule (its only consumer was elision). The
  `push`-of-a-gc-value RC_INC special case is gone (the bug class cannot recur
  without RC). Drop tables (owned + LGc kinds) are untouched — the gc mask is
  what feeds the collector's root maps.
- emit.ml: emit_rc, the v_rc view, the escape-acquire anchor, and every
  caller deleted; assignment displacing a traced value emits nothing (the VM's
  store barrier owns it); scope-ended LGc handles clear their gc-mask bit so
  root maps stay precise.
- .wob v4: WOB_VERSION 3 -> 4 in wob.h + emit.ml + disasm.ml + the runner's
  loader battery; opcodes 27-28 removed from the enum/jump table/interpreter
  and REJECTED by the loader like any unknown opcode.
- dump.ml: the == RC == owner-dump section is gone; 6 goldens re-blessed
  (owner dumps lose the section, elision.wo's bc dump loses its RC ops).
- runner.ml: rc-table/ELIDED assertions deleted; the elision test now asserts
  the WHOLE image contains no RC op; the table-contract sweep asserts rc ops
  never appear.
- test_unwind.c: the rc-opcodes test becomes two — the loader rejects reserved
  opcode 27, and an abandoned traced instance is freed by rt_destroy
  (ASan-proven).

Verified: woc-test 540/0 + test_diag 14/0; runtime test + test-iso all suites
ASan/UBSan (test_unwind 12/0); cli_smoke; oop-e2e 79/0 (v4 images end to end);
employee 8/0; log-watcher 7/0; ring runs + reclaimed (freed=3) with zero RC
ops in its image; `just oop-accept` ALL CRITERIA MET.

07bcc1c485 fix(compiler): demand promotion targets the escaping projection's class
The escape hook promoted the borrow-root local's class, so `return h.box`
over-promoted the container `Holder` alongside `Box`. Now `owner.ml`'s
`transfer` passes the escaping place's type (`place_ty p`) as `~promote_class`,
so only the value that actually escapes is promoted.

- escape: takes ~promote_class; records it in collect mode, else reports WO-E304.
- borrow-escape.wo now promotes only Box (was Box + Holder); rc.wo sans @gc
  still promotes Cache.

Verified: woc-test 566/0, test_diag 14/0, oop-e2e 79/0.

26771e6aa4 feat(compiler): demand promotion — GC-ness fully inferred (7b Phase 2b core)
Structural inference (2a) covers cyclic classes; this adds the DEMAND half for
the acyclic-but-aliased case, so @gc is now redundant everywhere.

- owner.ml: a `promote` sink on ctx. In collect mode, a class value that would
  raise WO-E304 (escape) records its class instead of erroring — because a
  class that MUST escape cannot be owned (second-class borrows can't be stored
  or returned), so it must be traced. `class_of_ty` extracts the class from the
  escaping local's type. analyze/analyze_fn take ?promote.
- main.ml typecheck_all: after structural injection, a fixpoint runs ownership
  in collect mode over every file, unioning promotions into syms.traced (and
  every module table), before owner/emit see it. Terminates (promotions only
  grow, bounded by class count).
- gcinfer.render_final: --dump-gc now reads the authoritative is_gc_class
  (structural + demand + the remaining @gc bridge), with the reason.

Effect: a class that escapes is inferred `gc` with no annotation — e.g. `Cache`
(rc.wo sans @gc) shows `gc (alias escape (demand))`; `Box` returned out of
`leak` is promoted and the program is valid. No false positives: employee's
Department/Employee stay owned; the 566 goldens + 14 test_diag unchanged.

Corpus: compile-fail/borrow-escape-return reclassified to run/ (prints 1) —
returning a borrowed class is now legal under demand promotion; the fixture
encoded pre-7b behavior.

Verified: woc-test 566/0 + test_diag 14/0; oop-e2e 79/0; employee 8/0;
log-watcher 7/0.

NOT in this slice: removing the `@gc` KEYWORD (parser rejection + rewriting the
RC/@gc golden + test_diag assertions + moving the inference injection into the
library so unit tests see it) — coupled to Phase 3, which deletes the RC
machinery those tests cover. The ring still needs Phase 3 to RUN (nullable
`?Node` gcref path).

fa4b282934 feat(compiler): update-through-row + delete statement (9b cont.)
- `e.field = v` where e is a table row lowers to DB_UPDATE_FIELD
  (class, id, field, value) — the row's indexes maintained at the choke
  point; heap-object field assignment still emits SETF unchanged
- `delete <row>` expression: DB_DELETE(class, id), yields the id so it
  composes in `try delete x catch (e) nil` (restrict/trap surfaces
  catchably); Delete AST node threaded through type/owner/dump/emit
- disassembly-caught bug fixed: in tail position dst == the builtin
  window's first reg, so moving the id into dst clobbered the class id
  — reserve dst past the window (the emit_ctor guard)
- run/db-update-delete fixture; oop-e2e up, woc-test 566/0,
  log-watcher 7/0
- employee seed/list/staff/raise/drop now compile+run; only `report`
  (group-by aggregation + projection record) remains

144c16b223 feat(compiler): ref + backlink navigation in queries (9b cont.)
- `backlink C.f` field type: parsed, typed as `multi C`, and VIRTUAL —
  filtered out of the stored row layout (no column, omittable in
  ctor/insert), collected in clsrec.cr_backlinks
- reading a backlink (`d.staff`) lowers to DB_PROBE on the source
  class's index for the backing column (backlink_target resolves the
  (source class, index number); a backlink with no backing index has
  no efficient read)
- `ref C` navigation (`e.dept.name`) chains: a ref value is the target
  row's id, so a `Ref C` base navigates into C's fields exactly like a
  table-class value, routing to DB_GET_FIELD both in typecheck and emit
- query navigation source `from s in d.staff`: emit_query evaluates the
  nav expr to get its id-list instead of DB_SCAN; QNav typechecks with
  the range var bound to the navigation's element class
- fixture run/db-query-relations proves both directions; oop-e2e 75/0,
  woc-test 566/0, log-watcher 7/0
- still ahead for employee: order/take, group-by aggregates, projection
  records, delete + update-through-row

4df9a0108b feat(compiler): language-integrated query — scan/where/select (9b slice)
- Ast.Query node + parser: `from <v> in <src> where* [group..into] [order
  by] [take] select <e>`, positional `from` trigger so it stays a usable
  identifier; select stays grammar-owned (no DbStub conflict)
- typecheck: range var bound to the source table class; a table-class
  value is its row id at runtime but TYPES as the class, so `e.field`
  checks against the class fields; result is `multi <select-type>`;
  group/order/take/navigation diagnosed WO-E250 not-yet (honest edge)
- emit: `from/where/select` lowers to a bytecode LOOP over DB_SCAN's
  materialized id list — DB_GET_FIELD per column read, where-guards skip
  the push, select projects, result is a fresh multi; no plan tree, no
  SQL text (disassembly-provable)
- field access on a @table-class value routes to DB_GET_FIELD instead of
  GETF (clsrec.cr_is_table + is_table_class); non-table classes unchanged
  so log-watcher is unaffected
- the ASan-caught bug kept in a comment: a table-class query element is a
  SCALAR id, not an OWNED pointer — tagging the result multi OWNED dropped
  an id as a pointer (SEGV in wo_drop_obj)
- fixture run/db-query-scan (where-filter + select-whole + select-field);
  oop-e2e 74/0, woc-test 566/0, log-watcher 7/0
- SLICE scope: group-by aggregation, order/take, and ref/backlink
  navigation are the next chunk (employee report/staff/raise need them)

7374d4d807 feat: insert executes (iteration 9, Task 3) -- DB_STUB retires for insert
- compiler: `insert Class { ... }` is a typed Ast.Insert in statement
  AND expression position, sharing the ctor literal's field grammar;
  typechecked with the ctor's omittable rule; result = the row id (Int)
- owner pass: the engine copies at the row API, so an insert BORROWS
  its field values -- no transfer, no E304; node is trap-capable and
  carries a live-mask drop entry like DbStub did
- emit: builtin 61 window = class-id const + one slot per DECLARED
  field in declaration order; omitted defaults emitted, omitted ?scalar
  gets WO_NIL_SCALAR, other omitted optionals the zero word; fresh
  argument values reaped after (the push/set copy semantics)
- runtime: database/src/db.c executes via the choke-point row API;
  rt.db/rt.wal opaque handles on wo_rt; WO_DATA=<dir> = replay
  <dir>/shard-0.wal at boot + commit-before-ack per statement (the
  builtin's return IS the ack until iteration 8 ticks); failed commit
  un-applies the row and traps WO_T_IO; loader validates the class-id
  slot (variable window documented in wob.h + format doc)
- the promised diff: trap/pricing-set-price-db-stub is now
  run/pricing-set-price-insert printing engine-allocated ids;
  durability smoke prints 1,2 then 3,4 across two WO_DATA runs
- old "bare insert is an Ident" unit test rewritten to the new
  contract; runner's loader mirror accepts id 61; goldens re-blessed
- gates: oop-accept ALL CRITERIA MET, oop-e2e 71/0, woc-test 566/0,
  wovm-test green, log-watcher 7/0

c4c0880880 fix: Text is an owned value copied at every boundary (executable plan, Task 1)
Measured on the workload's supervisor mode, eight seconds, clean SIGTERM exit:
run 1 051 040 B in 24 allocations -> 2 112 B in 19; watch 128 B in 2 -> 64 B in
1. corpus 71/0, woc runtest 565/0, wovm unit gates green, just log-watcher 6/0.

- owner.ml: `oclass_of` called `Text` a builtin scalar, so it was Copy and NO
  Text local was ever dropped — that, not the missing stdlib table, was the
  leak. Text is now Owned, which forces an answer for what it does at an
  ownership boundary, and the answer is uniform: it is COPIED. Into a
  container (push/set/`m[i] = v`, already true), into a field (SETF), out of a
  function (return), into a binding (`let s = other`), and into a loop cursor.
  The source keeps its value; a freshly built Text stays the caller's and is
  dropped at the site
- owner.ml: resolve_callee answers for three shapes it never knew — reserved
  stdlib members, builtins, and a class's `static` members — so their results
  get a type, an owner and a drop
- vm/builtin: WO_B_TEXT_COPY, the one new builtin the rule needs; SETF copies a
  TEXT field in; emit copies a Text read out of a container, bound from a
  place, returned from a place, or loaded into a cursor, and drops a freshly
  built one after a copying store
- sysio.c: fs.read_all/net.read allocated their cap then relabelled the buffer
  with the short length — but wo_str_free sizes a block by its len (no size
  headers, obj.h), so a 1 MiB buffer wearing a 30-byte length went onto a
  32-byte free list and never came back. They copy out at the true size now
- two regressions the corpus caught, fixed in the same pass: a @gc value read
  out of a container is a plain borrow, not an rc-counted alias; and push's @gc
  escape is keyed on "push is not a user-declared fn" rather than "the callee
  did not resolve", which stopped being true once builtins resolved
- docs: Task 1 closed in the executable plan with its before/after numbers, and
  the status board's item 1 records the deeper root cause

ebf82ca9c0 feat: json encode/decode + as, .wob v2 class metadata — log-watcher compiles
docs/examples/log-watcher (1285 lines, 7 files) now compiles clean: 0
diagnostics, a 35KB .wob written. corpus 71/0, woc runtest 565/0, every wovm
unit gate green (both dispatch flavors).

- .wob v2: each class row gains three u32 per-field arrays — the field's NAME
  constant, the CLASS it refers to (or the json-raw marker), and a container
  field's ELEMENT kinds. json is then a runtime service driven by metadata
  instead of per-type generated code. loader/emitter/disassembler/test
  assembler all read and write v2; field-name constants are interned with the
  rest of the pool (interning during serialization silently loses them)
- runtime/src/json.c (new): encode by static kind + object headers + class
  table (nested records need no static knowledge); decode parses and BINDS
  straight into the target class — keys matched to field names, nested objects
  built as the field's class, arrays as a multi of the field's element kind,
  unknown keys skipped, absent keys nil. Malformed input is nil, never a trap
- `as`: `json.decode(text) as T` is the one cast this language has (WO-E403
  for any other `as`, and for a bare json.decode with no target type). Its
  result is `?T`, which is why the decode and the target are one instruction
- json.Value: a reserved type name for a value the source does not inspect —
  the raw JSON slice, kind TEXT, re-emitted verbatim by encode
- docs: 00-wob-format.md is now the v2 reference (class metadata, TRY/ENDTRY,
  the whole builtin surface, WO_T_IO); 08-builtin-surface.md documents the
  text/container builtins, the OS modules with their predeclared records, and
  json's two documented limits (Bool encodes 0/1, floats truncate)

b6d7d4c940 feat: map iteration (for k, v in m) + multi element writes
log-watcher parse errors 7 -> 3 (only `as` left); corpus 71/0, woc 565/0.

- wob.h/builtin.c/loader.c: WO_B_MULTI_SET — `m[i] = v` for a multi, dropping
  the element it replaces (the mirror of map_set, which the format doc's sugar
  rule already had; the "no element write" gap is closed)
- ast/parser: `for k, v in m` — the second name binds the value for that key
- types.ml/owner.ml: the two cursors take the map's key and value types; both
  are borrows of what the map owns, so neither is dropped per iteration
- emit.ml: map form lowers to len + key_at/val_at over slot indexes (insertion
  order, cont.h's parallel arrays), same loop skeleton as the multi form

0d5020a05d feat: nil literal + systems-stdlib text/container builtins
log-watcher diagnostics 272 -> 129 (parse errors 7, stdlib-module calls 49,
lowering gaps 72). corpus 71/0, woc runtest 565/0, wovm unit gates green.

- nil (haxe-parity Task 6's literal half): `nil` keyword, Ast.NilLit, lowered
  to the zero word for every `?T` — the representation the format doc already
  fixes ("a nullable field stores exactly what T stores and spells nil as 0"),
  so no boxing, no unbox on read, and every drop plan already skips it.
  Contextual on its destination in both type derivers, like `[]`/`{}`
- 23 new builtins (wob.h ids 16..38, loader arities, builtin.c): len, byte_at,
  print_err, starts_with, ends_with, index_of, last_index_of, substr, trim,
  to_lower, char_of, parse_int, split, split_ws, join, slice, pop, shift,
  sort, reverse, remove, key_at, val_at
  - fresh-Text/fresh-multi results allocate in the VM; `split`/`split_ws` fix
    their element kind (Text), `slice` copies its source's — and COPIES Text
    elements so a slice and its source never both own one value
  - pop/shift hand the element's ownership to the caller; remove drops the
    map's own key and value; key_at/val_at expose slot-ordered enumeration
    (what `for k, v in m` will lower onto)
  - parse_int is optional-shaped: unparseable is 0, `?Int`'s own nil
- obj.c/obj.h: wo_str_alloc (uninitialized Text of known length) so `join`
  builds its result in one allocation instead of one per element
- types.ml/emit.ml: builtin signatures, argument-shape requirements and
  return types for all 23 — the return table is also what classifies a `let`
  holding a fresh Text or multi as owned, so an omission there is a leak

c43fa388d9 feat: try/catch over the trap system (haxe-parity plan 8, Task 5)
VM catch frames + expression-form try/catch in the compiler. Uncaught traps
keep byte-for-byte today's surface. log-watcher parse errors 18 -> 7;
corpus 71/0, woc runtest 565/0, wovm unit gates green (both dispatch flavors).

- wob.h: WOP_TRY (A sBx: push catch frame, handler at pc+sBx) / WOP_ENDTRY;
  WO_B_ERR_FILL builtin (fills the catch record: 0 code, 1 line, 2 method,
  3 msg — the field-order contract with the compiler)
- vm.h/vm.c: catch stack (depth, handler pc, error reg) + the caught error;
  vm_unwind takes a stop depth, so a caught trap kills every frame above the
  catching one exactly as an uncaught trap would, then releases only what the
  try region owned in the catching frame (drop-entry diff against the handler
  pc) and resumes at the handler; RET/RET0 drop the catch frames of the frame
  they leave; TRAPF resumes instead of returning when the trap was caught
- builtin.c: err_fill allocates the method/msg Texts into the record the
  compiler owns, so the pending error never has to outlive the landing
- loader.c: TRY's handler target validated like a jump, error register like
  any register operand; err_fill arity
- lexer/token/ast/parser: `try`/`catch` keywords; `try expr catch (e) expr`
  and `catch (e) { block }`, newline allowed before `catch`; try binds looser
  than every operator, so `try a / b catch (e) 0` catches the division
- types.ml: predeclared `Error` record (merged table only), catch binding,
  arm-type agreement reported only when both arms are confidently typed
- owner.ml: analyze_try — the catch arm is an alternate flow join off the
  entry state, the error record is an owned handler-scope local
- emit.ml: TRY/body/ENDTRY/JMP + handler prologue (NEW Error, err_fill),
  join drops on both arms, `Error` class entry only for programs that catch

Driving goal: compile docs/examples/log-watcher (1285 lines of .wo).
Diagnostics on that program: 481 -> 379; parse errors 85 -> 18.
tests/corpus via scripts/oop-e2e.sh stays 71 checks / 0 failures.

  `map<K, V>` and `?T` annotate a local; new `ListLit`/`MapLit` expressions;
  `method_decl.is_static`; `field.pub_read`
- parser.ml: let annotations go through parse_field_ty; `[]`/`[a, b]` and
  `{}` literals in expression position; `static const`/`static fn` in class
  bodies (one token of lookahead — `static` stays an identifier);
  `pub(read) field: T`; a `;` ends a statement on its own, so one-line
  guard bodies (`{ skip(...); return; }`) parse
- emit.ml: list/map literals lower to multi_new/map_new + one multi_push per
  element, element kinds from the destination's declared type (WO-E403 with
  no typed destination, same rule multi_new already had); `static fn` gets a
  receiverless method record (arg_cnt = params) and lowers `Cls.fn(args)`
  through emit_direct with no `self`; a static can satisfy no interface
- types.ml: a written `let` annotation is now the authority for the binding's
  type (the only thing that types `[]`/`{}`/`nil`); `static_method_of` +
  static-call return types; method_info.is_static is wired from the AST
- owner.ml: container literals are fresh owned values, elements read in place
  (inherits push()'s open borrowed-element gap, noted in the code)
- plan doc: `Spec:` header line so planboard's lint accepts the plan

0df9b4fe31 feat(compiler): iteration 5 Tasks 1-4 — modules, language surface, switch, typedef records + enum variants
- Modules: `use`/`pub`, directory-as-module, per-module symbol resolution (a
  flat first-wins merge silently ran the wrong `pub fn` body), six reserved
  stdlib namespaces typed UNKNOWN-BUT-RESERVED.
- Surface: `and`/`or` (own precedence tier, short-circuit, Bool-only), `${}`
  interpolation desugared at parse time, `const`, break/continue with
  drop-correct exits, do-while, inline-fn rejection.
- switch expr/stmt: required `default` over scalars/Text, arm unification,
  EQ/EQS+JZ lowering, per-arm drop scopes with N-way JOIN-DROP; `default`
  sorted last by a shared lowering order (textual order made arms dead).
- typedef records: structural, same shape = one class entry; `?name: T`
  nullable-by-shape; emit_ctor fills omitted defaults; `type` as field name.
- Enum variants: all-bare unions = int ordinals; any-payload = one class
  entry per variant, tag IS the header class_id (no header field, no format
  bump); exhaustive switch without `default`; arity checked both directions.
- Payload escape modeled as move-out (pointer-kind fields only — a scalar
  escape is a copy); caller reaps owned heap temps passed by borrow: two
  unbounded LSan-blind leaks, 10.5 MB -> 1.5 MB flat over 300k iterations.
- Fixed en route, each with a RED repro: dead E209 builtin-arg check and
  `int_to_text` missing from both types.ml builtin tables (both segfaulted
  wovm), multi-file phantom double-report, emit_ctor's field temp clobbering
  dst in tail position (pre-existing), warnings swallowed without an error.
- Two fenced VM builtins: `int_to_text` (13), `variant_tag` (14).
- 14+565 unit (was 14+401), corpus 71 (was 32) plain and under wovm_asan,
  wovm-test + cli_smoke green. Log-watcher 307 -> 93 diagnostics (85 E101 /
  4 E207 / 1 E208 / 3 W202); the 5 non-E101 residuals await Task 7 grammar.

641a41e25c feat: milestone 1 complete — .wob emitter, conformance corpus, single binary; GC redesign specced
- `woc` now emits `.wob` that `wovm` runs: emit.ml lowers the typed,
  owner-annotated AST (scope-stack registers with a >64 WO-E401 diagnostic,
  Lua-style call windows, ICALL by slot, dedup const pool, drop maps, line
  tables, implicit terminators); disasm.ml backs `--dump-bc` goldens.
- Ownership lowering consumes the four owner tables verbatim; RESIDUAL is the
  only source of borrow ops, coalesced per operand. Review caught the emitter
  consuming only 2 of owner.ml's 4 residual producers — an assignment-anchored
  aliasing violation ran to exit 0 instead of trapping; fixed, plus a backstop
  raising WO-E404 for any residual region left unconsumed.
- Conformance harness `scripts/oop-e2e.sh` (`just oop-e2e`): four fixture
  kinds with exact outcomes — byte-exact stdout, one WO-E### anchored on
  `error CODE:`, numeric trap code, gc trace. 25 fixtures incl. pricing-demo
  logic, the ownership suite, and DB_STUB's parse-but-trap. `tests/` un-ignored
  so the corpus is actually tracked.
- `woc build` produces a self-contained binary: wovm copy + appended image +
  20-byte trailer, self-exec via /proc/self/exe. Verified relocated outside
  the repo, argless, and against adversarial trailer corruption.
- Milestone 1's five spec criteria all MET (`just oop-accept`). Criterion 3
  closed by WO-E405 — the entry must return `Int`, since program mode already
  says its return value is the exit code — which deletes the leak class
  without adding return-type metadata to the format. `gc/held-cycle` retired:
  an externally-held cycle is not expressible in a post-exit pump.
- New spec: inferred GC + incremental per-shard tri-color mark-sweep, retiring
  `@gc` and reference counting. Story gains iterations 7b (that work) and 9b
  (`@table`, relations, compiler-checked query); `.dev/reference` gains a
  sparse System.Linq checkout. Priority: 5→6→7 (log-watcher) then 7b, 8, 9, 9b.

3b4372b913 feat(compiler): MVS ownership pass + woc driver; drop Money/SKU/Float, reject abstract
Completes plan 2 Tasks 7-8. owner.ml: mutable-value-semantics flow analysis
producing the four plan-3 emitter tables (moves, drops incl. LIVE-MASK for trap
unwinding, rc with elision, residual borrow sites) plus WO-E301-304 two-site
diagnostics. Alias questions run over canonicalized places, so a double-mut
reached through let-bound aliases lands in the residual table like the direct
form; dump.ml's contract notes the emitter must coalesce guards per operand.
main.ml: directory discovery, cross-file programs (symbols merge before bodies
check), diagnostics ordered by (file,line,col), new WO-E214 for a name declared
in two files. New docs/plan/oop-vm/01-error-catalog.md (14 emitted + 10 reserved
codes), un-ignored so both plan tracks can cite it; justfile regains woc-*.

builtin_scalars is now the five that work: Int, Bool, Text, Timestamp, Id.
Money/SKU/Float and the abstract_types allowlist are gone — `abstract` never
lexed, and Float had no literal syntax and no wob kind, so no value could exist.
Fixtures and samples retype Money->Int, SKU->Text. The abstract newtype feature
is rejected outright (verdict row adopt->reject); haxe-parity Task 7 keeps `is`.

nullable-types-implementation.md corrected: ?T is plumbed but UNENFORCED
(E211-213 declared, never emitted; probe exits 0), handed to haxe-parity Task 6
as next work item. Records all 10 dead codes incl. E205 — interface satisfaction
is unchecked. crates/rt keeps its Money/SKU fixtures (opaque strings, Stage 2).

Gate: build warning-clean, 14 + 264 checks 0 failures, pricing golden exit 0,
docs/examples histograms unchanged (13/70, zero WO-E225).
